increases by 7%. These results are justified by the
importance of lumber demand that represents almost
80% of the total network demand. Thus, it becomes
essential to plan the supply chain efficiently in order
to deliver the right product to the right customer
with the right quality. By managing quality
standards (freshness) it becomes also possible to
offer a more advantageous and stable price.
6 CONCLUSIONS
This article proposes an integrated model to plan
supply chain operations for the forest industry while
considering key constraints related to the freshness
of the wood fibre. In particular, we analyze a case
study, which includes four sawmills and one paper
mill located in eastern Canada. To ensure a better
use of the wood fibre and a greater synchronization
of the network activities, the model provides
harvesting, transportation, production, and storage
plans for the forest companies of this region. The
model aims at improving the management of the
wood fibre quality while reducing the operating
costs such as storage, transportation, and processing.
The proposed model has been tested using three
different scenarios: variations of the wood freshness,
different patterns of lumber demand, and variations
of the lumber price. Results show that the wood
fibre freshness is a key criterion to consider for
increasing the benefit of the value network. On the
other hand, scenario analysis based on lumber price
and demand confirm the necessity for Canadian
forest product companies to expand their market to
avoid the effects of the relative instability of the
Canadian lumber market.
The next step will be to develop multiple models
based on a coordinated driving strategy for
addressing the fact that each company is
“independent” or autonomous. It will also be
necessary to develop some mechanisms to ensure a
fair benefit sharing generated of a better
synchronization of network members’ operations.
